- Introduce AST-based visitor and resolver in middleend
- Update guard field and parser to use AstNode<Expr>
- Remove backend variable_resolution and adjust exports
- Expose middleend in the library
The commit changes the interpreter and related code to use the new
`BaeValue` and `Number` types, moving away from direct floats. The main
changes include:
- Replace LiteralValue with BaeValue across the codebase - Add Number
enum for type-safe numeric values - Move AST definitions to common
module - Update operators to handle new numeric types - Add 'is' token
type and parser support Switch to common base_value library for value
types
This commit represents a significant refactoring to switch the
interpreter to use a new shared base value type system. The main changes
include:
1. Move value types to a new common/base_value.rs module 2. Add richer
numeric type support with promotion rules 3. Update interpreter to use
new BaseValue enum 4. Move AST types to common module for sharing 5.
Consolidate value operations like Add, Sub etc 6. Add proper test
coverage for numeric operations
The commit improves type safety and adds more robust numeric handling
while keeping the interpreter's core logic clean.
